NORWALK — The former operations manager of a Norwalk pediatric practice is back in police custody a year after being accused of stealing more than $15,000 from the employer.

Last year, Alexandra DiCamillo, 43, was accused of making fraudulent purchases totaling more than $15,000 on company credit cards, in addition to stealing a few thousand in petty cash. An investigation led to DiCamillo’s arrest In March 2018, and charges with second-degree larceny and 36 counts each of illegal use of a credit card and identity theft.

But police now believe her theft from her former employer, Advanced Pediatric Center, may have gone further than originally suspected.

In March 2019, an employee of the company contacted police to report that her social security number had been used to open a line of credit under DiCamillo’s name in October 2017. The complainant said she only learned of the account when the bank attempted to retrieve $800 in outstanding debt.

Detectives informed DiCamillo about the warrant for her arrest on Wednesday and later that day she turned herself in.

DiCamillo, of Heritage Hill Road, New Canaan, was charged with third-degree identity theft and illegal use of a credit card. She was held on $5,000 bond and given a court date of May 21. Her ealier charges are pending in court.
